No, for 2 reasons. 1. If 'Marathon' fails, there's nothing to suggest Bungie/Sony will suddenly decide it was a mistake and 'Destiny' will take priority above all else. 2. The 'Destiny' franchise, despite what some might desperately want to believe, is [b]NOT[/b] the only game available and when it does in fact die (because it will) gaming will continue regardless so people need to accept that this franchise doesn't dictate the video gaming market. Sony has plenty of arrows in their quiver, and the life or death of this game won't topple their empire.
